I recently lost my custom cover for my 18.5' bass boat, and I replaced it with this cover hoping that it would be a close fit. It actually fits better than my custom cover, and the 175 HP motor actually fits perfectly as well(much better than the original did). I can't attest to long term hold up, but it seems to be very well made. The elastic ends really help to give it a snug fit too. I am very pleased with my purchase.
